System for supplying an aircraft with inert gas, method for supplying an aircraft with inert gas, use of a membrane and aircraft

A method for supplying an aircraft with inert gas, comprising:

• channeling oxygen-depleted exhaust air from a fuel cell to an inlet of a membrane device that comprises a membrane and that guides the exhaust air from the inlet to an outlet;
• removing water vapor issuing through the membrane;
• and
• channeling dried exhaust air issuing from the membrane device to inert a space;
• wherein the membrane device is constructed as an exhaust air pipe,
• wherein the membrane is arranged on an external surface of the exhaust air pipe and is in fluid communication with a flow cross-section of the exhaust air pipe, and
• wherein a fuel line is arranged within the exhaust air pipe.

An aircraft, comprising:

• a system that supplies the aircraft with inert gas, the system including at least one fuel cell with an air inlet and an exhaust air outlet, a membrane device with an inlet, an outlet and a vapor-permeable membrane,
• wherein the exhaust air outlet is in fluid communication with the inlet of the membrane device, and the membrane device is adapted for guiding a gas from the inlet to the outlet and to give off to an outside through the membrane any water vapor contained therein, and
• wherein the membrane device is designed as an exhaust air pipe that is installed in a ventilated region of the aircraft;
• wherein the membrane device is constructed as an exhaust air pipe,
• wherein the membrane is arranged on the external surface of the exhaust air pipe and is in fluid communication with a flow cross-section of the exhaust air pipe, and
• wherein a fuel line is arranged within the exhaust air pipe.
